BACKGROUND Field of the Disclosure

The disclosure relates generally to an information handling system, and in particular, generating and managing fingerprint templates for fingerprint sensors of an information handling system.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

This disclosure discusses methods and systems for generating and managing fingerprint templates for fingerprint sensors of an information handling system. In short, a fingerprint management computing module can receive a fingerprint image from a fingerprint sensor. The fingerprint sensor can be included by any computing peripheral coupled to the information handling system, or part of the information handling system. The fingerprint management computing module can apply multiple fingerprint template creation models to the single fingerprint image to generate respective fingerprint templates. The fingerprint templates can each be associated with differing types and size requirements of other fingerprint sensors. These fingerprint templates can then be used for validation of other fingerprint images that may be obtained at a later time.

Specifically, this disclosure discusses a system and a method for generating and managing fingerprint templates for fingerprint sensors of an information handling system, including receiving a fingerprint image of a user that is obtained at a first fingerprint sensor; identifying a plurality of fingerprint template creation models, each fingerprint template creation model associated with a respective other fingerprint sensor, each other fingerprint sensor differing from one another and differing from the first fingerprint sensor; applying each of the fingerprint template creation models to the fingerprint image to generate respective fingerprint templates; associating, for each generated fingerprint template, i) an identification (ID) of the other fingerprint sensor that corresponds to the fingerprint model that generated the fingerprint template and ii) a user identification (ID) of the user associated with the fingerprint image obtained at the first fingerprint sensor; and storing each of the generated fingerprint templates in a database.

In some embodiments, processor subsystem 120 may interpret and/or execute program instructions and/or process data stored locally (e.g., in memory subsystem 130 and/or another component of information handling system). In the same or alternative embodiments, processor subsystem 120 may interpret and/or execute program instructions and/or process data stored remotely (e.g., in network storage resource 170).

Also in FIG. 1, memory subsystem 130 may comprise a system, device, or apparatus operable to retain and/or retrieve program instructions and/or data for a period of time (e.g., computer-readable media). Memory subsystem 130 may comprise random access memory (RAM), electrically erasable programmable read-only memory (EEPROM), a PCMCIA card, flash memory, magnetic storage, opto-magnetic storage, and/or a suitable selection and/or array of volatile or non-volatile memory that retains data after power to its associated information handling system, such as system 100, is powered down.

In information handling system 100, I/O subsystem 140 may comprise a system, device, or apparatus generally operable to receive and/or transmit data to/from/within information handling system 100.

Likewise, the network storage resource may comprise computer-readable media (e.g., hard disk drive, floppy disk drive, CD-ROM, and/or other type of rotating storage media, flash memory, EEPROM, and/or other type of solid state storage media) and may be generally operable to store instructions and/or data.

In FIG. 1, network interface 160 may be a suitable system, apparatus, or device operable to serve as an interface between information handling system 100 and a network 110. Network interface 160 may enable information handling system 100 to communicate over network 110 using a suitable transmission protocol and/or standard, including, but not limited to, transmission protocols and/or standards enumerated below with respect to the discussion of network 110. In some embodiments, network interface 160 may be communicatively coupled via network 110 to a network storage resource 170. Network 110 may be a public network or a private (e.g. corporate) network. The network may be implemented as, or may be a part of, a storage area network (SAN), personal area network (PAN), local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a wireless local area network (WLAN), a virtual private network (VPN), an intranet, the Internet or another appropriate architecture or system that facilitates the communication of signals, data and/or messages (generally referred to as data). Network interface 160 may enable wired and/or wireless communications (e.g., NFC or Bluetooth) to and/or from information handling system 100.

In particular embodiments, network 110 may include one or more routers for routing data between client information handling systems 100 and server information handling systems 100. A device (e.g., a client information handling system 100 or a server information handling system 100) on network 110 may be addressed by a corresponding network address including, for example, an Internet protocol (IP) address, an Internet name, a Windows Internet name service (WINS) name, a domain name or other system name. In particular embodiments, network 110 may include one or more logical groupings of network devices such as, for example, one or more sites (e.g. customer sites) or subnets. As an example, a corporate network may include potentially thousands of offices or branches, each with its own subnet (or multiple subnets) having many devices. One or more client information handling systems 100 may communicate with one or more server information handling systems 100 via any suitable connection including, for example, a modem connection, a LAN connection including the Ethernet or a broadband WAN connection including DSL, Cable, Ti, T3, Fiber Optics, Wi-Fi, or a mobile network connection including GSM, GPRS, 3G, or WiMax.

Network 110 may transmit data using a desired storage and/or communication protocol, including, but not limited to, Fibre Channel, Frame Relay, Asynchronous Transfer Mode (ATM), Internet protocol (IP), other packet-based protocol, small computer system interface (SCSI), Internet SCSI (iSCSI), Serial Attached SCSI (SAS) or another transport that operates with the SCSI protocol, advanced technology attachment (ATA), serial ATA (SATA), advanced technology attachment packet interface (ATAPI), serial storage architecture (SSA), integrated drive electronics (IDE), and/or any combination thereof. Network 110 and its various components may be implemented using hardware, software, or any combination thereof.

The information handling system 100 can also include a fingerprint management computing module 190. The fingerprint management computing module 190 can be included by the memory subsystem 130. The fingerprint management computing module 190 can include a computer-executable program (software). The fingerprint management computing module 190 can be executed by the processor subsystem 120.

In short, the fingerprint management computing module 190 can receive a fingerprint image from a fingerprint sensor. The fingerprint sensor can be included by any computing peripheral coupled to the information handling system 100, or part of the information handling system 100. The fingerprint management computing module 190 can apply multiple fingerprint template creation models to the single fingerprint image to generate respective fingerprint templates. The fingerprint templates can each be associated with differing types and size requirements of other fingerprint sensors. These fingerprint templates can then be used for validation of other fingerprint images that may be obtained at a later time.

Turning to FIG. 2, FIG. 2 illustrates an environment 200 including an information handling system 202, for fingerprint enrollment. The information handling system 202 can include a fingerprint management computing module 210, a storage device 212, a storage device 214, and fingerprint sensors 216 a, 216 b, . . . , 216 n (collectively referred to as fingerprint sensors 216). In some examples, the information handling system 202 is similar to, or includes, the information handling system 100 of FIG. 1. In some examples, the fingerprint management computing module 210 is the same, or substantially the same, as the fingerprint management computing module 190 of FIG. 1. In some examples, any of the fingerprint sensors 216 are the same, or substantially the same, as the fingerprint sensor 192 of FIG. 1.

The fingerprint management computing module 210 can be in communication with the storage device 212, the storage device 214, and the fingerprint sensors 216.

In some examples, each of the fingerprint sensors 216 can differ from one another. That is, each of the fingerprint sensors 216 can be of a specific type (e.g., Goodix or Synaptic) and include a particular sensor size (e.g., 4×4 or 10×10). For example, one of the fingerprint sensors 216 can be included by (associated with) the information handling system 202 and have a 10×10 sensor size. For example, one of the fingerprint sensors 216 can be included by (associated with) a keyboard input device and have a 6×6 sensor size. For example, one of the fingerprint sensors 216 can be included by (associated with) a mouse input device (handheld input device) and have a 4×4 sensor size.

The information handling system 202, and in particular, the fingerprint management computing module 210, can generate and manage fingerprint templates for the fingerprint sensors 216, described further herein. In other words, the fingerprint management computing module 210 can facilitate providing a “one-to-many” fingerprint login experience that allows authentication from the multiple fingerprint sensors 216 each having respective differing fingerprint sensor technologies.

In some examples, the fingerprint sensor 216 a obtains a fingerprint image 230 a of a user 220, at step A. For example, the fingerprint sensor 216 a can include a fingerprint sensor of the information handling system 202 (e.g., integrated into a body of the information handling system 202). However, the fingerprint sensor 216 a can be included by any device (e.g., input/output device) coupled to the information handling system 202, such as a keyboard or mouse.

The fingerprint management computing module 210 can obtain the fingerprint image 230 a from the fingerprint sensor 216 a, at step B. The fingerprint management computing module 210, when obtaining the fingerprint image 230 a, can additionally obtain a sensor identification (ID) 232 a of the fingerprint sensor 216 a. The sensor ID 232 a can uniquely identify the fingerprint sensor 216 a, including a sensor size of the fingerprint sensor 216 a and a type of the fingerprint sensor 216 a (such as Goodix or Synaptic), or technology type of the fingerprint sensor 216 a. The fingerprint management computing module 210 can further perform verification of the fingerprint image 230 a (e.g., based on a stored/secured key). In some examples, the fingerprint management computing module 210 encrypts the fingerprint image 230 a.

The fingerprint management computing module 210 can identify fingerprint template creation models 240 a, 240 b, . . . , 240 n (collectively referred to as fingerprint template creation models 240), at step C. Specifically, the storage device 212 can store the fingerprint template creation models 240. Each of the fingerprint template creation models 240 are associated with a respective fingerprint sensor 216. For example, the fingerprint template creation model 240 a is associated with the fingerprint sensor 216 a; the fingerprint template creation model 240 b is associated with the fingerprint sensor 216 b; and the fingerprint template creation model 240 n is associated with the fingerprint sensor 216 n.

Moreover, each fingerprint template creation model 240 is associated with a sensor size requirement of the respective fingerprint sensor 216 that the fingerprint template creation model 240 is associated with. For example, the fingerprint template creation model 240 a is associated with a sensor size requirement of the fingerprint sensor 216 a (e.g., 4×4 sensor size); the fingerprint template creation model 240 b is associated with a sensor size requirement of the fingerprint sensor 216 b (e.g., 6×6 sensor size); and the fingerprint template creation model 240 n is associated with a sensor size requirement of the fingerprint sensor 216 n (e.g., 10×10 sensor size). The sensor size requirements can be included in metadata (included by metadata) associated with each fingerprint template creation model 240. In some examples, the sensor size requirements of each fingerprint template creation model 240 differs.

The fingerprint management computing module 210 can apply each of the fingerprint template creation models 240 to the fingerprint image 230 a, at step D. Specifically, the fingerprint management computing module 210 can apply each of the fingerprint template creation models 240 to the fingerprint image 230 a to generate respective fingerprint templates. For example, the fingerprint management computing module 210 can apply the fingerprint template creation model 240 a to the fingerprint image 230 a to generate the fingerprint template 250 a; the fingerprint management computing module 210 can apply the fingerprint template creation model 240 b to the fingerprint image 230 a to generate the fingerprint template 250 b; and the fingerprint management computing module 210 can apply the fingerprint template creation model 240 n to the fingerprint image 230 a to generate the fingerprint template 250 n.

In some examples, the fingerprint management computing module 210 can apply each of the fingerprint template creation models 240 to the fingerprint image 230 a by performing parallel feature extraction of the fingerprint image 230 a against each of the fingerprint template creation models 240 to generate the respective fingerprint templates 250. Thus, the single fingerprint image 230 a can be matched against different sensor models (e.g., different fingerprint sensors 216) by way of the fingerprint templates 250.

The fingerprint management computing module 210 associates, for each generated fingerprint template 250, a fingerprint sensor identification (ID) of the fingerprint sensor 216 that corresponds to the fingerprint template creation model 240 that generated the fingerprint template 250, at step E. For example, the fingerprint template 250 a is associated with the sensor ID 260 a (sensor ID 260 a being the ID of the fingerprint sensor 216 a); the fingerprint template 250 b is associated with the sensor ID 260 b (sensor ID 260 b being the ID of the fingerprint sensor 216 b); and the fingerprint template 250 n is associated with the sensor ID 260 n (sensor ID 260 n being the ID of the fingerprint sensor 216 n).

Moreover, the fingerprint management computing module 210 associates, for each generated fingerprint template 250, a user identification (ID) 270 of the user 220, at step E. For example, the fingerprint templates 250 a, 250 b, 250 n are each associated with the user ID 270. Thus, each of the fingerprint templates 250 are associated with a single user ID 270.

The fingerprint management computing module 210 stores each of the generated fingerprint templates 250 at the storage device 214, at step F. That is, the fingerprint management computing module 210 stores the fingerprint templates 250 in a database at the storage device 214. The fingerprint management computing module 210 stores the fingerprint templates 250 and the associations (correspondence) of the fingerprint templates 250 with the respective sensor IDs 260; and further stores the fingerprint templates 250 and the association (correspondence) with the single user ID 270 for each of the fingerprint templates 250.

In some examples, the fingerprint management computing module 210 can identify the sensor ID 232 a of the fingerprint sensor 216 a. In response, the fingerprint management computing module 210 can identify a fingerprint template 250 that is associated with the sensor ID 232 a of the fingerprint sensor 216 a. For example, the fingerprint management computing module 210 can identify the fingerprint template 250 a as being associated with (or corresponding to) the sensor ID 232 a. That is, the fingerprint template 250 a was previously generated prior to receiving/obtaining the fingerprint image 230 a. For example, the fingerprint management computing module 210 generates the fingerprint template 250 a as described herein.

The fingerprint management computing module 210 can update the (previously generated) fingerprint template 250 a based on the fingerprint image 230 a. Specifically, the fingerprint management computing module 210 can identify the fingerprint template creation model 240 a that is associated with the sensor ID 232 a; apply the fingerprint template creation module 240 a to the fingerprint image 230 a to generate a further fingerprint template. The fingerprint management computing module 210 can merge, or concatenate, the previously generated fingerprint template 250 a with the further fingerprint template—updating the previously generated fingerprint template 250 a.

Referring to FIG. 3, the environment 200 is shown for requesting fingerprint authentication. Specifically, the fingerprint sensor 216 b obtains a fingerprint image 230 b of the user 220, at step A. For example, the fingerprint sensor 216 b can include a fingerprint sensor of a keyboard input device coupled to the information handling system 202.

The fingerprint management computing module 210 can obtain the fingerprint image 230 b from the fingerprint sensor 216 b, at step B. The fingerprint management computing module 210, when obtaining the fingerprint image 230 b, can additionally obtain the sensor identification (ID) 232 b of the fingerprint sensor 216 b. Thus, the fingerprint management computing module 210 determines (identifies) the sensor ID 232 of the fingerprint sensor 216 b. The fingerprint management computing module 210 can further perform verification of the fingerprint image 230 b (e.g., based on a stored/secured key). In some examples, the fingerprint management computing module 210 encrypts the fingerprint image 230 b.

The fingerprint management computing module 210 communicates with the storage device 214, at step C. The fingerprint management computing module 210 identifies the fingerprint template 250 b from the generated fingerprint templates (that are stored at the storage device 214), at step D. Specifically, the fingerprint management computing module 210 identifies the fingerprint template 250 b (that is stored at the storage device 214) that is associated with a sensor ID 260 b that matches the sensor ID 232 b of the fingerprint sensor 216 b. That is, the fingerprint management computing module 210 compares the sensor ID 232 b that is received with the fingerprint image 230 b (the sensor ID 232 b indicating the fingerprint sensor 216 b) with each of the sensor IDs 260 that is stored by the storage device 214. The fingerprint management computing module 210, based on the comparing, can identify the sensor ID 260 b that matches the sensor ID 232 b. Based on such matching, the fingerprint management computing module 210 can identify the fingerprint template 250 b that is associated with (corresponds to) the sensor ID 260 b. In some examples, the fingerprint management computing module 210 can determine whether the fingerprint image 230 b matches with the fingerprint template 250 b. For example, the fingerprint management computing module 210 can perform vector-based matching or minutia-based matching between the fingerprint image 230 b and the fingerprint template 250 b. In some examples, the fingerprint management computing module 210 can provide the fingerprint template 250 b to any application or the operating system for matching of the fingerprint image 230 b with the fingerprint template 250 b.

In some examples, the fingerprint management computing module 210 can decrypt the fingerprint image 230 b. For example, prior to identifying the fingerprint template 250 b, the fingerprint management computing module 210 can decrypt the fingerprint image 230 b (when the fingerprint image 230 b is encrypted).

FIG. 4 illustrates a flowchart depicting selected elements of an embodiment of a method 400 for generating and managing fingerprint templates for fingerprint sensors of an information handling system, including fingerprint enrollment. The method 400 may be performed by the information handling system 100, the information handling system 202 and/or the fingerprint management computing module 210, and with reference to FIGS. 1-3. It is noted that certain operations described in method 400 may be optional or may be rearranged in different embodiments.

The fingerprint management computing module 210 receives the fingerprint image 230 a of the user 220 that is obtained at the fingerprint sensor 216 a (402). The fingerprint management computing module 210 identifies the fingerprint template creation models 240 (404). In some examples, each fingerprint template creation model 240 is associated with a respective fingerprint sensor 216. In some examples, each of the fingerprint sensor 216 differs from one another. The fingerprint management computing module 210 applies each of the fingerprint template creation models 240 to the fingerprint image 232 a to generate respective fingerprint templates 250 (406). The fingerprint management computing module 210 associates, for each generated fingerprint template 250, i) the fingerprint sensor ID 260 that corresponds to the fingerprint model 240 that generated the fingerprint template 250 and ii) the user ID 270 of the user 220 associated with the fingerprint image 232 a obtained at the fingerprint sensor 216 (408). The fingerprint management computing module 210 stores each of the generated fingerprint templates 250 at the storage device 214 (410).

FIG. 5 illustrates a flowchart depicting selected elements of an embodiment of a method 500 for generating and managing fingerprint templates for fingerprint sensors of an information handling system, including fingerprint authentication. The method 500 may be performed by the information handling system 100, the information handling system 202 and/or the fingerprint management computing module 210, and with reference to FIGS. 1-3. It is noted that certain operations described in method 500 may be optional or may be rearranged in different embodiments.

The fingerprint management computing module 210 receives an additional fingerprint image 230 b of the user 220 that is obtained at the fingerprint sensor 216 b (502). The fingerprint management computing module 210 determines the sensor ID 232 b of the fingerprint sensor 216 b (504). The fingerprint management computing module 210 identifies the fingerprint template 250 b from the generated fingerprint templates 250 that is associated with the sensor ID 260 b that matches the sensor ID 232 b of the fingerprint sensor 216 b (506).

FIG. 6 illustrates a flowchart depicting selected elements of an embodiment of a method 600 for generating and managing fingerprint templates for fingerprint sensors of an information handling system. The method 600 may be performed by the information handling system 100, the information handling system 202 and/or the fingerprint management computing module 210, and with reference to FIGS. 1-3. It is noted that certain operations described in method 600 may be optional or may be rearranged in different embodiments.

The fingerprint sensor 216 initiates fingerprint capture (602). The fingerprint sensor 216 captures the fingerprint image 230 (604). The fingerprint sensor encrypts the fingerprint image 230 (606). The fingerprint management computing module 210 identifies the sensor ID 230 (608). The fingerprint management computing module 210 determines whether the fingerprint image 230 is for enrollment or verification (610). If the fingerprint management computing module 210 determines that the fingerprint image 230 is for enrollment, the fingerprint management computing module 210 updates the fingerprint template 250 (612). The fingerprint management computing module 210 determines whether all of the fingerprint sensors 216 are enrolled (614). If all of the fingerprint sensors 216 are enrolled, the process ends. If all of the fingerprint sensors 216 are not enrolled, the process returns to step 602. If the fingerprint management computing module 210 determines that the fingerprint image 230 is for verification, the fingerprint management computing module 210 applies the fingerprint template creation models 240 to the fingerprint image 230 (616). The fingerprint management computing module 210 generates the fingerprint templates 250 (618).
